    The procedure in the national Phase

    CH.01 EFFECT OF A DESIGNATION OF SWITZERLAND OR LIECHTENSTEIN
    Under the Patent Treaty between Switzerland and Liechtenstein only a unitary patent for the two States can be granted; in an international application, therefore, the designation of either State automatically has the effect of the designation of both States, which cannot be designated independently from each other.
    CH.02 LANGUAGE OF PROCEEDINGS
    PatG Sec. 131(2),
    PatV Art. 4(1),
    PatV Art. 4(3),
    PatV Art. 4(4)

    The language of proceedings is one of the official languages (French, German or Italian). If the international application has been filed in French or German, the language of proceedings is French or German, as the case may be; if not, the language of the translation which is furnished to the Office under PCT Article 22 or 39(1) is the language of proceedings. The language of proceedings cannot be changed. Written matter other than the text of the application is usually accepted in any of the official languages, but the Office reserves the right to request a translation into the language of proceedings.
    CH.03 TRANSLATION (CORRECTION)
    Errors in the translation of the international application can be corrected with reference to the text of the international application as filed (refer to National Phase, paragraphs NP 6.002 and NP 6.003). If the translation furnished to the Office is not complete, the Office will invite the applicant to furnish the missing part and will excuse the late furnishing.

    PatG Sec. 138,
    PatV Art. 34,
    PatV Art. 124(1)

    If the name and address of the inventor have not already been furnished in the “Request” part of the international application, the applicant must furnish the inventor’s name and address and make a declaration of inventorship on the form reproduced in Annex CH.II. Certification is not required. The declaration of inventorship must be written in or translated into one of the official languages (French, German or Italian) or in English. For time limits, refer to the Summary.
    CH.05 ADDRESS FOR SERVICE
    PatG Sec. 13,
    PatV Art. 124

    Where the applicant has neither a residence nor a principal place of business in Switzerland, an address for service in Switzerland must be indicated (article 13 of the Federal Law on Patents for Inventions (PatG) within the time limit set out in paragraph 1 of article 124 of the Ordinance on Patents for Inventions (PatV). If no address for service is indicated within that time limit, the Office will allow an extension of three months to do so. The application will be refused in case of non-observation of that time limit.

The ten first claims made in a patent application are exempted of any fees; a claims fee is due for each supplementary claim. For the amount of the claims fee, refer to Annex CH.I.
    CH.09 ANNUAL FEES
    PatG Sec. 41,
    PatV Art. 18

    They are payable for the fourth and each subsequent year following the international filing date. The payment of the first annual fees is due on the last day of the month in which falls the fourth anniversary (48 months) of the international filing date. Thereafter, payment must be made within six months from the last day of the month in which falls the anniversary of the international filing date; a supplement for late payment must be paid if the fee is paid during the last three months. For the amounts, refer to Annex CH.I.
    CH.10 EXAMINATION FEE
    PatG Sec. 41,
    PatV Art. 61a

    This fee must be paid for each international application. It is due before the start of the examination as to substance, on invitation and within the time limit fixed by the Office. Where a request to postpone the examination as to substance has been made before the invitation or is made within the time limit for payment, that time limit is extended until the expiration of the postponement.
    CH.11 AMENDMENT OF THE APPLICATION
    PCT Article 28,
    PatG Sec. 58(2),
    PatG Sec. 59a(1)

    The applicant may amend the description, claims and drawings of the international application.

    CH.14 EXCUSE OF DELAYS IN MEETING TIME LIMITS

The request for continuation of the procedure must be presented within two months from the time when the applicant became aware of the failure to meet the time limit, but not later than six months from the expiration of the time limit which has not been observed. Additionally, the omitted act must be completed and the fee for continuation of the procedure must be paid within the same time limit. Continuation of the procedure is excluded in some cases provided for under PatG Section 46a and PatV Article 14, in particular for time limits for payment of the transmittal fee, the search fee and the international fee as well as for the time limit for election of States. Contrary to a request for reinstatement (refer to paragraph CH.16), the applicant is not required to prove that he was prevented, through no fault of his own, from complying with the time limit.
    CH.16
    PatG Sec. 47,
    PatV Art. 15

    Reinstatement may be requested where the applicant, through no fault of his own, has failed to comply with a time limit during the international phase or before the Office. Reinstatement is excluded, however, where the missed time limit is the time limit for requesting reinstatement. The request for reinstatement must be presented within two months after removal of the cause of non-compliance with the time limit but not later than one year from the expiration of the time limit which has not been observed. Within these two months, the omitted act must be completed, the reinstatement fee (refer to Annex CH.I) must be paid and a statement of the facts on which the request is based must be furnished.
